The invention belongs to the field of
medicine, and provides an
aprepitant micelle composition and a preparation method thereof, the
aprepitant micelle composition is composed of an
active component aprepitant and auxiliary materials such as
phospholipid,
cholic acid or a salt thereof, a nano-
micelle stabilizer, a pH
regulator and the like, the
dosage form is a freeze-dried
powder injection, and the
solubility of the aprepitant is remarkably improved; the combination of the nano-micelle stabilizer can significantly improve the stability of the preparation, avoids the use of a large amount of
soybean oil for solubilization, and reduces the risk of
hyperlipidemia.
Ethanol is not contained, so that
ethanol anaphylaxis is avoided, and the safety of clinical medication can be remarkably improved. After the freeze-dried
powder injection is redissolved, a hot-pressing sterilization mode can be adopted, so that the sterile guarantee level is remarkably improved, and the clinical
medication risk is reduced. The aprepitant micelle composition is prepared by adopting a tert-butyl
alcohol-water freeze-
drying method, the process is simple and convenient, large-scale production is easy, a common freeze-dried
powder injection
production line can be adopted, special equipment such as a high-pressure
homogenizer and a special
fat emulsion production line are not needed, and the production cost can be remarkably reduced.
